MP1720 2.7W, Mono Class-D, Low-EMI, High-Efficiency Audio Amplifier DESCRIPTION FEATURES The MP1720 is a high efficiency Class-D audio Passes FCC-Radiated Emissions Standards amplifier. It utilizes a full bridge output structure with 24inch of Cable without output filter capable of delivering 2.7W into 4 speaker. 2.7W Into 4 with 5V VIN 10% THD+N This device exhibits the high fidelity of a class Up to 90% Efficiency AB amplifier with an efficiency of 90% which Flexible Switching Frequency setting dramatically reduces solution size by integrating Low Noise (53V Typical) with 3.3V VIN the following: 15ms Start-up time Eliminates pop Low Quiescent Current (4mA 3.3V) 250m power MOSFETs (V =3.3V) IN Low Shutdown Current (0.1A) Startup / Shutdown pop elimination Full Bridge Output Drive Short circuit /Thermal overload Protection Fully Differential Input The MP1720 features a pin-selectable 1MHz or Short circuit Protection 1.3MHz frequency control or can be Thermal Shutdown synchronized to an external clock source. The flexible switching frequency and internal EMI- APPLICATIONS reduction scheme eliminates the need for an Cellular Phones output LC filter and passes emission standards PDAs without filter & with considerable cable. MP3 Players The MP1720 has five fixed gain options. Portable Audio MP1720-3: 3dB MP1720-6: 6dB MP1720-9: All MPS parts are lead-free and adhere to the RoHS directive. For MPS green 9dB MP1720-12: 12dB MP1720-216: 21.6dB. status, please visit MPS website under Products, Quality Assurance page.
